| Abstract: | In a hydroponics experiment, sulfate uptake kinetic parameters of 34 genotypes of maize (28 hybrids and 6 inbreeds) were evaluated by using 35 S trace technology. It was found that the differences among genotypes were highly significant. Grain yield and total sulfate absorbtion were also investigated, so was the relationship between sulfate uptake kinetic parameters and the effect of sulphur fertilizer application. The results indicated that sulfate uptake kinetic parameters could be used as an effective physiological indicator for screening efficiency in sulfate uptake and utilization of maize genotypes. |
